    Lipid nanoparticle siRNA treatment of Ebola-virus-Makona-infected nonhuman primates (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-04-23
    Description: The current outbreak of Ebola virus in West Africa is unprecedented, causing more cases and fatalities than all previous outbreaks combined, and has yet to be controlled. Several post-exposure interventions have been employed under compassionate use to treat patients repatriated to Europe and the United States. However, the in vivo efficacy of these interventions against the new outbreak strain of Ebola virus is unknown. Here we show that lipid-nanoparticle-encapsulated short interfering RNAs (siRNAs) rapidly adapted to target the Makona outbreak strain of Ebola virus are able to protect 100% of rhesus monkeys against lethal challenge when treatment was initiated at 3 days after exposure while animals were viraemic and clinically ill. Although all infected animals showed evidence of advanced disease including abnormal haematology, blood chemistry and coagulopathy, siRNA-treated animals had milder clinical features and fully recovered, while the untreated control animals succumbed to the disease. These results represent the first, to our knowledge, successful demonstration of therapeutic anti-Ebola virus efficacy against the new outbreak strain in nonhuman primates and highlight the rapid development of lipid-nanoparticle-delivered siRNA as a countermeasure against this highly lethal human disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4467030/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4467030/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thi, Emily P -- Mire, Chad E -- Lee, Amy C H -- Geisbert, Joan B -- Zhou, Joy Z -- Agans, Krystle N -- Snead, Nicholas M -- Deer, Daniel J -- Barnard, Trisha R -- Fenton, Karla A -- MacLachlan, Ian -- Geisbert, Thomas W -- U19 AI109711/AI/NIAID NIH HHS/ -- U19AI109711/AI/NIAID NIH HHS/ -- England -- Nature. 2015 May 21;521(7552):362-5. doi: 10.1038/nature14442.

    Interleukin-22 promotes intestinal-stem-cell-mediated epithelial regeneration (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-12-10
    Description: Epithelial regeneration is critical for barrier maintenance and organ function after intestinal injury. The intestinal stem cell (ISC) niche provides Wnt, Notch and epidermal growth factor (EGF) signals supporting Lgr5(+) crypt base columnar ISCs for normal epithelial maintenance. However, little is known about the regulation of the ISC compartment after tissue damage. Using ex vivo organoid cultures, here we show that innate lymphoid cells (ILCs), potent producers of interleukin-22 (IL-22) after intestinal injury, increase the growth of mouse small intestine organoids in an IL-22-dependent fashion. Recombinant IL-22 directly targeted ISCs, augmenting the growth of both mouse and human intestinal organoids, increasing proliferation and promoting ISC expansion. IL-22 induced STAT3 phosphorylation in Lgr5(+) ISCs, and STAT3 was crucial for both organoid formation and IL-22-mediated regeneration. Treatment with IL-22 in vivo after mouse allogeneic bone marrow transplantation enhanced the recovery of ISCs, increased epithelial regeneration and reduced intestinal pathology and mortality from graft-versus-host disease. ATOH1-deficient organoid culture demonstrated that IL-22 induced epithelial regeneration independently of the Paneth cell niche. Our findings reveal a fundamental mechanism by which the immune system is able to support the intestinal epithelium, activating ISCs to promote regeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4720437/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4720437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindemans, Caroline A -- Calafiore, Marco -- Mertelsmann, Anna M -- O'Connor, Margaret H -- Dudakov, Jarrod A -- Jenq, Robert R -- Velardi, Enrico -- Young, Lauren F -- Smith, Odette M -- Lawrence, Gillian -- Ivanov, Juliet A -- Fu, Ya-Yuan -- Takashima, Shuichiro -- Hua, Guoqiang -- Martin, Maria L -- O'Rourke, Kevin P -- Lo, Yuan-Hung -- Mokry, Michal -- Romera-Hernandez, Monica -- Cupedo, Tom -- Dow, Lukas E -- Nieuwenhuis, Edward E -- Shroyer, Noah F -- Liu, Chen -- Kolesnick, Richard -- van den Brink, Marcel R M -- Hanash, Alan M -- HHSN272200900059C/PHS HHS/ -- K08 HL115355/HL/NHLBI NIH HHS/ -- K08-HL115355/HL/NHLBI NIH HHS/ -- K99 CA176376/CA/NCI NIH HHS/ -- K99-CA176376/CA/NCI NIH HHS/ -- P01 CA023766/CA/NCI NIH HHS/ -- P01-CA023766/CA/NCI NIH HHS/ -- P30 CA008748/CA/NCI NIH HHS/ -- P30-CA008748/CA/NCI NIH HHS/ -- R01 AI080455/AI/NIAID NIH HHS/ -- R01 AI100288/AI/NIAID NIH HHS/ -- R01 AI101406/AI/NIAID NIH HHS/ -- R01 HL069929/HL/NHLBI NIH HHS/ -- R01 HL125571/HL/NHLBI NIH HHS/ -- R01-AI080455/AI/NIAID NIH HHS/ -- R01-AI100288/AI/NIAID NIH HHS/ -- R01-AI101406/AI/NIAID NIH HHS/ -- R01-HL069929/HL/NHLBI NIH HHS/ -- R01-HL125571/HL/NHLBI NIH HHS/ -- U19 AI116497/AI/NIAID NIH HHS/ -- England -- Nature. 2015 Dec 24;528(7583):560-4. doi: 10.1038/nature16460.

    Thermosensory processing in the Drosophila brain (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-03-06
    Description: In Drosophila, just as in vertebrates, changes in external temperature are encoded by bidirectional opponent thermoreceptor cells: some cells are excited by warming and inhibited by cooling, whereas others are excited by cooling and inhibited by warming. The central circuits that process these signals are not understood. In Drosophila, a specific brain region receives input from thermoreceptor cells. Here we show that distinct genetically identified projection neurons (PNs) in this brain region are excited by cooling, warming, or both. The PNs excited by cooling receive mainly feed-forward excitation from cool thermoreceptors. In contrast, the PNs excited by warming ('warm-PNs') receive both excitation from warm thermoreceptors and crossover inhibition from cool thermoreceptors through inhibitory interneurons. Notably, this crossover inhibition elicits warming-evoked excitation, because warming suppresses tonic activity in cool thermoreceptors. This in turn disinhibits warm-PNs and sums with feed-forward excitation evoked by warming. Crossover inhibition could cancel non-thermal activity (noise) that is positively correlated among warm and cool thermoreceptor cells, while reinforcing thermal activity which is anti-correlated. Our results show how central circuits can combine signals from bidirectional opponent neurons to construct sensitive and robust neural codes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Wendy W -- Mazor, Ofer -- Wilson, Rachel I -- R01 DC008174/DC/NIDCD NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2015 Mar 19;519(7543):353-7. doi: 10.1038/nature14170.

    G-protein-independent coupling of MC4R to Kir7.1 in hypothalamic neurons (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-01-21
    Description: The regulated release of anorexigenic alpha-melanocyte stimulating hormone (alpha-MSH) and orexigenic Agouti-related protein (AgRP) from discrete hypothalamic arcuate neurons onto common target sites in the central nervous system has a fundamental role in the regulation of energy homeostasis. Both peptides bind with high affinity to the melanocortin-4 receptor (MC4R); existing data show that alpha-MSH is an agonist that couples the receptor to the Galphas signalling pathway, while AgRP binds competitively to block alpha-MSH binding and blocks the constitutive activity mediated by the ligand-mimetic amino-terminal domain of the receptor. Here we show that, in mice, regulation of firing activity of neurons from the paraventricular nucleus of the hypothalamus (PVN) by alpha-MSH and AgRP can be mediated independently of Galphas signalling by ligand-induced coupling of MC4R to closure of inwardly rectifying potassium channel, Kir7.1. Furthermore, AgRP is a biased agonist that hyperpolarizes neurons by binding to MC4R and opening Kir7.1, independently of its inhibition of alpha-MSH binding. Consequently, Kir7.1 signalling appears to be central to melanocortin-mediated regulation of energy homeostasis within the PVN. Coupling of MC4R to Kir7.1 may explain unusual aspects of the control of energy homeostasis by melanocortin signalling, including the gene dosage effect of MC4R and the sustained effects of AgRP on food intake.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383680/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383680/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghamari-Langroudi, Masoud -- Digby, Gregory J -- Sebag, Julien A -- Millhauser, Glenn L -- Palomino, Rafael -- Matthews, Robert -- Gillyard, Taneisha -- Panaro, Brandon L -- Tough, Iain R -- Cox, Helen M -- Denton, Jerod S -- Cone, Roger D -- 5R01 DK082884-03/DK/NIDDK NIH HHS/ -- DK020593/DK/NIDDK NIH HHS/ -- F31 DK102343/DK/NIDDK NIH HHS/ -- P30 DK020593/DK/NIDDK NIH HHS/ -- R01 DK064265/DK/NIDDK NIH HHS/ -- R01 DK070332/DK/NIDDK NIH HHS/ -- R01DK064265/DK/NIDDK NIH HHS/ -- R01DK070332/DK/NIDDK NIH HHS/ -- R25 GM059994/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Apr 2;520(7545):94-8. doi: 10.1038/nature14051.

    Two insulin receptors determine alternative wing morphs in planthoppers (2015)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2015-03-25
    Description: Wing polyphenism is an evolutionarily successful feature found in a wide range of insects. Long-winged morphs can fly, which allows them to escape adverse habitats and track changing resources, whereas short-winged morphs are flightless, but usually possess higher fecundity than the winged morphs. Studies on aphids, crickets and planthoppers have revealed that alternative wing morphs develop in response to various environmental cues, and that the response to these cues may be mediated by developmental hormones, although research in this area has yielded equivocal and conflicting results about exactly which hormones are involved. As it stands, the molecular mechanism underlying wing morph determination in insects has remained elusive. Here we show that two insulin receptors in the migratory brown planthopper Nilaparvata lugens, InR1 and InR2, have opposing roles in controlling long wing versus short wing development by regulating the activity of the forkhead transcription factor Foxo. InR1, acting via the phosphatidylinositol-3-OH kinase (PI(3)K)-protein kinase B (Akt) signalling cascade, leads to the long-winged morph if active and the short-winged morph if inactive. InR2, by contrast, functions as a negative regulator of the InR1-PI(3)K-Akt pathway: suppression of InR2 results in development of the long-winged morph. The brain-secreted ligand Ilp3 triggers development of long-winged morphs. Our findings provide the first evidence of a molecular basis for the regulation of wing polyphenism in insects, and they are also the first demonstration--to our knowledge--of binary control over alternative developmental outcomes, and thus deepen our understanding of the development and evolution of phenotypic plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Hai-Jun -- Xue, Jian -- Lu, Bo -- Zhang, Xue-Chao -- Zhuo, Ji-Chong -- He, Shu-Fang -- Ma, Xiao-Fang -- Jiang, Ya-Qin -- Fan, Hai-Wei -- Xu, Ji-Yu -- Ye, Yu-Xuan -- Pan, Peng-Lu -- Li, Qiao -- Bao, Yan-Yuan -- Nijhout, H Frederik -- Zhang, Chuan-Xi -- England -- Nature. 2015 Mar 26;519(7544):464-7. doi: 10.1038/nature14286.
